- The All-Out Attack. Technologically superior forces aim their weapons of war and three legged walkers at Earth, which bravely fights back, driving them off through cunning, bravery, or just dumb luck... most of the time.
- The Infiltration. Aliens are replacing, brainwashing, or controlling humans in order to take over from within. Generally, the populace at large doesn't even know it's happening. May involve The Virus.
- A combination of the above, with an infiltration paving the way for an all-out attack.
Sometimes, there are good aliens that help us against the invaders; unfortunately, they tend to be much weaker and/or less numerous, since if they were equally or more powerful, the focus would be taken off humanity. Then there's the Benevolent Alien Invasion, where the invaders are the good aliens.
Often an allegory for some Earth-based conflict, either one that's happened in the past or one that people fear may happen. The Infiltration is especially popular as a metaphor for Communism.
This trope, in its modern form, was created by H. G. Wells's novel War of the Worlds. It was actually a variation on another theme popular at the time, the "invasion story", where another country's army, usually France or Germany (depending on who relations were worse with at the time), would try to conquer Britain. Then World War I happened. Today, similar themes are found in techno-thrillers, and crop up in works like Red Dawn and The Tomorrow Series.
A common Tomato Surprise nowadays is for the invaders to be human.

Anime & Manga

- Battlefield Earth: Has two of them, one a thousand years before the book starts when the evil Psychlos took over the planet, and then a coalition of other races swoop in after humanity retakes Earth.

- The Puppet Masters by Robert A. Heinlein: A novel made into several movies.

They are also really, conservative. Like, they've been ruled by the same dynasty for tens of thousands of years and are surprised that humans have advanced from the medieval era to the present in only a few hundred years, conservative.
Live Action TV
- Dark Skies: A series on FOX was pretty much a textbook type 2, infiltrating with parasites and (at the end) electronic implants. The point of the series was that many of the events of the 20th century were secretly part of the infiltration, such as the Kennedy assassination.
- Doctor Who: Uses all three variants of invasion. The series also inverts this tropes in many future-based stories, humans are themselves the invaders. We're usually not outright malicious, but we're often quite destructive to native species, paralleling historical imperialism and colonization.
- Falling Skies: A TNT Show takes place about six months after an alien invasion devastates most major cities and wipes out a large percentage of the population. The show describes a ragtag group of survivors trying to find food and shelter to get by, while avoiding murderous aliens and roving bands of outlaws and trying to survive and fight back. While the series avoids showing the actual invasion (the background is told by a child and a series of drawings in the pilot), it involves huge circular Ominous Floating Spaceships appearing over major cities. They hang there for a while, but the world leaders decide not to strike first, hoping the aliens are friendly. They aren't. The ships emit powerful EMP waves, shutting down power grids and defense systems before proceeding to obliterate most major cities. They land ground troops with infantry and mechs (the survivors note that the mechs are bipedal, despite the aliens having 6 legs) that proceed to wipe out much of the adult population, while capturing children and putting Mind Control harnesses on them (presumably, to make them slaves). The large ships depart, while the invading forces begin constructing large structures in places of destroyed cities. The human survivors are forced to retreat and use only basic weaponry (rifles, machineguns, and C4), as any heavy munitions tend to piss off the aliens, and their bombers simply level the entire area.

- One episode revealed that the government was secretly preparing for an alien attack, building a series of satellites armed with nukes which were set to face away from Earth.
- Invasion: A 2005 ABC show is a bizarre case of the infiltration type in which the main aliens are seen only as glowing orange lights in the water, but the infiltrating "hybrids" have the exact appearances (sans scars or other non-genetic marks) and memories of the dead humans they replace. This makes (most of) them unaware that they are are infiltrating aliens. It was cancelled after one season, so the actual goals of the invaders are never made clear.
- The Outer Limits both versions did several infiltration invasion plots.
- One episode dealt with a group of people locked in bunkers completely unaware of what was happening in the world. The last thing they heard was that a fleet of alien ships was heading for Earth with suspicions that they were here to colonize. The episode ends with only one of these people alive, as he is preparing to be rescued, unaware that the invasion has already succeeded.
- Star Trek: The Next Generation and Star Trek: First Contact: The Borg invasions of Earth Shout Outs to The War of the Worlds (e.g. one of the ships fighting the Borg is named Thunder Child).

- "The Invaders" (1967) with Roy Thinnes as a man who accidentally sees a flying saucer land and can't convince people that we've been invaded. They use the infiltration method, altering their bodies to look like humans. Because of the year there was a lot of heavy handed storylines involving race and the youth culture.

- Weird Al Yankovic wrote Slime Monsters from Outer Space, which is a version 1.

- Achron: The game starts immediately after the greatest space fleet humanity has ever assembled has been all but completely destroyed by the alien invaders. They did this despite actually being outnumbered and outgunned by the human forces. It turns out that Time Travel actually gives you a hell of an advantage.
- City of Heroes: Takes place in the aftermath of an extra dimensional alien invasion, which was hard-won and remnants of the Rikti forces still infest the world. And of course, it turns out that the Rikti are mutated humans. BUT, that leads into another possible future invasion by different aliens. The Rikti's weakness? Magic. The Shiva in Bloody Bay are the remains of a planet-devouring entity that was destroyed in deep space but is now trying to rebuild itself by conquering Earth for its resources.
- Command and Conquer 3: Tiberium Wars marks the debut of the Scrin, whose arrival throws the ongoing GDI-Brotherhood of Nod conflict into chaos and force the two sides to work together. But it's more complicated than an "All-Out Attack" example: the Scrin are trying to harvest the Tiberium they seeded the Earth with, and expected for the xenoforming crystals to have wiped out the planet's indigenous population, but Kane tricked them into arriving early. The Scrin expedition is actually a mining operation, not a formal army, and once they're driven back by the humans they vow to return with a proper invasion force... a Sequel Hook utterly ignored by Command & Conquer 4.
- The Conduit : The game subverts this trope. It starts off with an invasion by the Drudge, a race of Big Creepy-Crawlies. Later, it is revealed that the invaders are actually human-created clones as part of a Government Conspiracy.

- Duke Nukem 3D with an all out assault and in Duke Nukem Forever the aliens come back. And they come back angry.
- Ecco the Dolphin: Both game storylines involve aliens. In the first game, the Vortex aliens have been content to just suck up critters from Earth's seas every 500 years, but after Ecco beats them, their Queen follows him back to Earth in the second game, where she and her children proceed to mess everything up. Eventually, she flees back in time to infiltrate Earth from there. Word of God has it that it worked, but not the way she wanted it to; the Vortex lose their identity as a species and give rise to arthropods. The third game involves some completely different aliens called the Foe; their time travelling shenanigans actually work to change Earth's future, until Ecco stops them.
- Gungrave: The "infiltration" method is used in the games. A race of parasitic aliens called "Methuselah" came to the planet eons ago and just wanted to infect all living things with the substance that the main characters know as the designer drug called "Seed". It turns humans and animals into mindless mutants subservient to the alien consciousness. It was these beings that manipulated and corrupted Harry in the original game, provided the technology that created the Necrolization Project, and gave Garino, the Big Bad of Overdose, power beyond imagination. Garino was even planning to leave the planet to continue spreading seed.
- Half-Life: Is about aliens coming through a portal to Earth, albeit unintentionally (though given the chance, the Nihilanth was more than happy to conquer, or try it anyway). The second is set in a Dystopia where different aliens came through and defeated Earth.
- Halo: Follows the "All-Out Attack" example, with The Covenant attacking Earth colonies before finally taking the fight to Earth. In order to prevent an alien invasion, all ships that are losing a battle are commanded to wipe their memory banks and self-destruct, denying the aliens knowledge of human colony locations, as well as Earth. In the end the Covenant find Earth anyway though they were looking for something else, but this particular strategy allowed humanity to fight for years, when otherwise they would have been defeated in weeks or months.
- Iji Starts six months after the almost all-out attack has succeeded. Then looms the danger of a really all-out attack.
- Mario and Luigi: Partners In Time The main plot has the Mario Bros. team up with their infant selves to thwart the invasion of the alien Shroobs.
- Mass Effect: The Reapers, the Man Behind the Man in Mass Effect 1 and Mass Effect 2 in the threats to the galaxy at large, directly assault earth in a massed invasion in the opening of Mass Effect 3.
- Mega Man Star Force : In the game, with interesting takes on the infiltration variation. In the story, alien life forms, called FM-ians, must fuse with humans who are very lonely thru manipulation in order to attack other people. This is because being energy waves they have no physical form and thus can't harm physical beings under normal circumstances. They can't even be seen normally. Fusing with humans allows the FM-ian to materialize and thus cause physical harm. They can also disrupt electronic devices or if there is enough electromagnetic energy being emitted, turn people into energy waves to attack them.
- Metal Slug 2: The Mars People arrive War of the Worlds style aliens who attack using flying saucers. When they're driven off, one of them impersonates Morden and tries to use the Rebellion Army as a weapon in Metal Slug 3. Once that's uncovered, the heroes attack their mothership and destroy their leader, Rootmars. Properly chastised, the Mars People become a bit more peaceful, and serve as allies in the sixth game to fight an invasion from Beneath the Earth that considers them snack food.
- Starcraft: the Terrans are facing two invasions: the Zerg and Protoss. The Zerg favor infiltration infestation) as a way to soften up targets for the Swarm. The Protoss, on the other hand, employ a range of tactics, from "shoot missiles at it" through "shoot more missiles at it" past "throw in lasers for good measure" and on to "screw it, let's just sterilize the planet". Notable in all of this is the Battle of Tarsonis, where the Zerg, Protoss, and Terran rebels all try the All-Out Attack on the poor planet at the same time. The Protoss were not as much invading the Terrans as they were containing the Zerg who would then perform an all out invasion on the Protoss.
- Universe At War: Earth Assault: An all out attack, In a subversion, humanity fails utterly at repelling the invading Hierarchy and are reduced to bit players, forced to watch as a race of mechanical Laser Guided Tykebombs arrive on Earth and the ancient Atlanteans awake, both species intent on bloody revenge against the Hierarchy for crimes committed against them in the past.
- X-COM: The various aliens in the game series are generally set on utterly destroying humanity. The infiltration method they attempt in the first game was merely a tactic toward the goal of total destruction.
- The Inexplicable Adventures of Bob: Subverted, where the Nemesites have legally owned Earth since before mankind even evolved. Until we develop good enough technology to leave Earth, they don't particularly care whether or not we know they own the planet. Space Pirates do attack Earth once, not to conquer it but to randomly steal stuff. Nemesite Princess Voluptua comes to stop them, informing them, "Earth is a nature preserve, you feebs! This isn't even piracy--It's poaching!"
- Titanzer: They not only invaded but punched the head off the statue of liberty.
- Morando's forces invade Arcadia in the Grand Finale of 3Below.
- Ben 10: Alien Force first season finale climaxed with the Highbreeds beginning their planned invasion of Earth. Oddly enough, they so much as fought off as convinced to stop when the heroes learn their invading due to being a Dying Race whose genetics won't let them repopulate. It isn't until Ben uses the Omnitrix to mix various alien species with their own, saving them, that they call off their attack.
- Futurama: Happens from time to time. To paraphrase a comic:
- Invader Zim: The show is about an alien using the infiltration method. He's really bad at it. However the Irkens are really good at what they're doing, no matter how bad Zim is. We've seen them successfully take over several planets and they seem to run a galactic monopoly that can't be challenged by any other being in the Universe (to our knowledge).
- Jimmy Neutron: Three separate times. The first time the Yokians arrived to Earth they stole every adult in Retroville (except Miss Fowl) only to take them to their planet. The second time they arrived on Earth they successfully earned everyone's trust and tried to kill off all the adults once more. Then there is Grandma Tater's, who's apparently one of many similar aliens that take over planets using hypnosis.
- Justice League:
- The very first story arc, "Secret Origins", sees the Justice League come together for the first time to combat shapeshifting aliens. Initially, the aliens infiltrate society to undermine Earth's defense systems, then they begin their All-Out Attack. The Good Alien role is filled by J'onn J'onnz, the sole survivor of a Martian civilization that these invaders had destroyed centuries ago.
- The Season Two Grand Finale "Starcrossed" sees the League nearly destroyed by another invasion. The Thanagarian infiltration was far more effective, because they had a Mole in the Justice League itself, providing them with the information to neutralize its members. These invaders initially present themselves as the Good Aliens, claiming that they're fortifying Earth to defend it from their enemies; the real Good Alien turns out to be their Mole, Hawkgirl, who learns of their true intentions for Earth and is unable to go through with it.
- The JLU episode "Dark Heart", in which the League faces Grey Goo from outer space.
- The JLU Grand Finale "Destroyer" has Darkseid leading the forces of Apokolips on an All-Out Attack on Earth. The League is forced to temporarily team up with the remaining members of the Legion of Doom in order to fight them off.
- Kim Possible: The Grand Finale had the previously once introduced Scary Dogmatic Aliens invade Earth for rather no real reason at all. All they did was send in Humongous Mechas while the two aliens just sat and relaxed. Rather than an "official" government-backed invasion, it appears that the whole attack was simply a private vendetta against Drakken/Earth on the part of Warmonga.
- Little Audrey cartoon "Dizzy Dishes": In Audrey's dream there are alien invaders attacking with a disintegrator.

- The Simpsons did this many times with Kang and Kodos. The best was prior to the 1996 presidential election where they kidnap Clinton and Dole and take their places (infiltration method). In the end they are discovered but still win because they have both major candidates and "It's a two party system. You have to vote for one of us." Someone suggests voting for a third party candidate: Alien: Sure, THROW your vote away!" In the end they are our rulers.
